The effect of adenoidectomy or adenotonsillectomy on occlusal features in mouth-breathing preschoolers.

Purpose: The purpose of this study was to evaluate mouth-breathing and nasal-breathing children prior to surgical intervention and 28 months postoperatively, comparing the occlusal features obtained pre- and postoperatively through orthodontic study casts.

Methods: The mouth-breathing (MB) group consists of 33 MB children who underwent surgery and presented a nasal-breathing (NB) pattern after surgery. The control group comprised 22 NB children.

Changes in facial morphology after adenotonsillectomy in mouth-breathing children.

Background: Morphological and dentofacial alterations have been attributed to impaired respiratory function.

Objective: To examine the influence of mouth breathing (MB) on children facial morphology before and after adenoidectomy or adenotonsillectomy.

Methods: Thirty-three MB children who restored nasal breathing (NB) after surgery and 22 NB children were evaluated.

Cephalometric assessment of the mandibular growth pattern in mouth-breathing children.

Objective: At the present time, it is generally accepted that chronic mouth breathing influences craniofacial growth and development. The objective of this study was to determine the position of the jaw, its growth direction and morphology, and the facial proportions of children with two different etiological factors of mouth breathing, at different age groups.

Materials And Methods: Four groups of mouth breathing children were analyzed by cephalometry.
